I got a new Compaq laptop last month from my parents as a present for becoming a student. They also installed me DSL Internet connection. Then a future colleague installed me Torrent software for movie downloading. At the beginning, everything was good. Since yesterday, my Internet connection is slow. Do I maybe have a virus? Did Sygate Firewall let virus on my PC?
I think that you are infected. It is probably the infection with some sort of Downloader or Trojan virus. Its job is to aloud access to hard drive content on your computer to his owner. Those viruses are common on the Internet. I had to reinstall my OS twice because of torrent using. That was at the beginning. However, from my personal experience I found out what to use for protection. The protection that I have been using for last couple of months is combination of AVG and Seagate Personal firewall. Only way Sygate could let virus on your PC is if you tell him to do that accidentally. You should let access to your PC only to well known softwares. Now you should first use AVG from the Safe mode to clean all viruses from your computer and then, install Seagate Personal firewall.
